I must do something wrong. I strictly followed your instructions, installing Clover as you said (picture)in esp . I always get a boot0 error and I'm forced to boot from usb. I don't know why. Actually I can say that everything works but bluetooth and wifi (of course) and that I can't adjust brightness though I installed Native display. Buttons work (shift F1 and F2) but nothing changes but this thing it's a p.i.t.a. I would like to boot from laptop. Thanks for your help as usual.

@Matthew82 I noticed something that maybe could help us.
Your SSDT partly works with me, I explain:
Without your SSDT the UAD App to manage my devices crashes if I turn off one (the last in the chain).
With your SSDT, if I connect to port 1 of my PCI card and turn off one of the connected devices (the last one in the chain), the UAD application does not crash and continues to show me the devices that remained turned on.
If I connect to port 2 instead, and I do the same, the app crashes.
You say your SSDT works on Asus pci Thunderbolt cards. The Asus ThunderboltEX card has a single Thunderbolt 3 port, while other manufacturers such as Gigabyte and ASRock have two. And if the problem is this?
Now your SSDT is in the system. Here's what IOReg shows when I'm connected to Thunderbolt port 1:
Lele’s iMac Thunderbolt port 1.zip
This however, when I use the Thunderbolt port 2:
Lele’s iMac Thunderbolt port 2.zip
Is it possible to concentrate the SSDT so that it loads only one Thunderbolt Port?

send me new dump with new files
this way is: we need a x86platform, but if u have kp with AppleIntelCPUPowerManagement...is wrong, need a patches to kernel, like x99, etc, procs without a native support
i think ur GPU loose suppoort in new systems, buy other, check a cost benefit for sierra and high sierra

I have GA-Z170X-Gaming_7 with i7 6700.
I integrated TB 3.
I do not have a TB 3 device.
I connected the iPhone to this port.
Can you create an SSDT on this basis?
How can I create an SSDT?
Can anyone help me with this? Please.
Thanks.

Hi guys, please if anoyne know how to fix.
recently I succesfully insaled HS on my desktop using @MaLd0n guide
Everything works, except my system freezes after playing Youtube/Facebook videos, no metter what browser I'm using (FF, Chrome, Safari). Strange is that occurs only if I'm fast forwarding on certain video, skiping, it just freezes, keyboard don't work, mouse works, but can't on anything.
I have fully hardware acceleration (checked with some program, forgot the name, VODsomething)
Other thing I noticed, that my PC won't POST sometimes, but when I unplug the SSD wich contains HS on it, it boots normaly, then I recconect my drive and aagin I can boot back in HS.

@morpheousman If I look at my sytems... Optiplex 755
Optiplex 790
But pushing an older system, like the 755, 760 and 780 to it's limits has its charms.
The 755 still runs very well on High Sierra, albeit a little slower than the 790 (obviously)

the process is not finished, the progress bar is in an indeterminate state, bacause it's waiting for the actual creation process to finish, and also there is a notification at the end of the process, but yes that progress bar lloks to similar to a full progressbar, so i am considering doing something else, because when it goas into an indetermante state, i have no data to determinate the % of completetion of the process, so i have to use a system which indicates that something is going on but, not at which % it is

I did an upgrade from OS X 10.10.5 to OS X 10.11 on iMac late 2012 and experienced same issue as yours. Then I did an Erase, Format and install of OS X 10.11 (from USB Installer Disc) - all worked fine for 2 weeks and then the same problem reappeared.
I solve my problem going back to to Yosemite and will remain there until 10.11.1 or maybe 10.11.2 is released

Many thanks, It works, not really quite but it's working. I had to download again HSierra, created a new stick, bios upgrade.
Trying to patch dsdt!! (is this the same as the one on el capitan or i need on High Sierra a new one??)
